No More Ants

Living in TX we have a really bad ant problem. This product has kept the ants out of my apartment. Specifically my 10yr old's room, which he shares with our dog. I feel better using this product which is derived from plants and is safer than using Raid.

Checks all of the boxes

[This review was collected as part of a promotion.] We've been using this for an about a month now and I love it. Consider it spot treatment for outdoor pests. My husband and I love spending time on our front porch and this spray has been such a lifesaver for us. Since we have 3 dogs that like to lounge with us being pet friendly is a must and this one checks all of the boxes

Perfect for ants!

[This review was collected as part of a promotion.] This STEM spray has been perfect for getting rid of ants in my house. I love that you can use it indoor and outdoor. Since it's plant based, I feel more comfortable with spraying it in the house around my dogs opposed to other brands. It's super effective, works so quickly, and easy to clean. The scent is also not overwhelming! The bottle is easy to use and definitely worth the money.

Solid outdoor use

[This review was collected as part of a promotion.] It's fly time in the summer, so I've sprayed this outside on our exterior doors. First, it seems to do a decent job of deterring most bugs. It definitely smells like a bug spray, that citronella-y smell? Not unpleasant but I don't think I'd want it in the house. We'll continue to use it through bug season to minimize bugs coming through our open doors and windows!

Ant be gone

I came across this item online and decided to purchase it because I was having a problem with ants in my kitchen. I was searching for a product that was safe to spray because my cat likes to explore. I used this spray and it worked. It's been a couple weeks now and I haven't seen any ants in the kitchen. I like the fact that it doesn't have that strong chemical smell. The scent is mild and you barely even notice its. This is a product I will definitely purchase again.

Safer option

[This review was collected as part of a promotion.] Seems to work well. I like the fact that it's a safer choice than other ant and roach sprays out there. Safety is a big factor for my household. The only issue really can be the residue it leaves.

Works

[This review was collected as part of a promotion.] I love scent it's very strong and lasting though lol but it's effective too we have beetles that sit at the door spread all of them and they dropped real quick I don't like the mist of it so be careful where you spray 🤣

Good for pets. Bad scent.

[This review was collected as part of a promotion.] I am happy it's good around pets and people but the smell of it is very overwhelming. It does appear effective I didn't have many bugs at the time but the ones that I did it seemed to do well. It's a good price as well.

Affordable bug spray

[This review was collected as part of a promotion.] Its a pretty effective bug spray as i used it around spraying the areas i normally get ants or flies and I've less of them. The spray however stays sort of like an acid or oil for a long time after so be warned. Not strong smelling and fairly easy to use.

Messy

I honestly don't know if this product works because you have to spray the insect and it's an oily spray. I'm not spaying this on furniture, drapery, etc. The only safe place to spray is the counter so you can safely clean it after. I returned it.
